DITCHING APPRATUS.

Application area somber as, w22.Y ser-iai No. 595,328.

To all whom t ymfffz/ concern:

e it known that l. (nLviN S. PARKER, of the city of London, in the countyof dlesex, Province of Ontario. Canada, a sub ject of the King of (treat ritain, have invented certain new and useful Improvements in @itching Apparatus. of which the following is a speciication. n

This invention relates to ditching machine of the type in which a ditch dug' and the soil elevated by buckets travelling in a closed orbit, and in which a shoe is provided connected to the frame behind tl e orbit of theV buckets adapted to smooth .i trench tom for the reception. of dr tile. an y. object is to devise means adapted for with ditching apparatus of this type whe by the dug soil may be .zarricd reaiwvardl and re-deposited in the ditch on top of the tile, thus saving the laborof tilting in the soil as a separate operation after it hasbeen deposited on the spill bank in the ordinary o manner. A further objectvis to so arrange the apparatus that the dug soil may .be deposited on the spill bank whenever contitions render it desirable. l

l attain iuy object by means of the constructions hereinafter described and illustrated in the accompanying drawings in whichf Fig. l. is a plan view of a ditching machine constructed iu accordance with my in vention g A Fig. 2 a side same; and f .Fig 3 an endview partly in section.

In the drawings like numerals ofreference indicate corresponding parts vin the different gures. 1 f l is the frame yon which theditching wheel is journalled. W'hile the method ofjournalv ling is in'imalerial as far. as the present in?.v vention is concerned. show a pluralitybf rollers 2 engaging the inner periphervv the Yrim 3 of the d ching wheel., being journalled on the-frame y the frame l. The ditching wh spokeless and the transverse conveyor 5 if' thus extend throughthe wheelV to recr-ivetlie vexcavated soil which drops from the buckets 6v ofthe ditching wheel when they reach. the top. The transverse conveyoris driven by means of bevel gearing 7 from theV shaft 8 iournalled on the frame 1 and which serves to drive 'theV ditching wheel through the ine; dium of the pinion 9 which meshes with a elevation of part of the seen eel is thus botvsidewalls of the di gear 10 formed Lon they ditching wheel. This# shaft in practiceis. driven vfrom the tractor which forms lpart of the complete inaeliine,A but which is not shown or described yas 'it forms no part of the'present invention.

Behind the ditchino' wheel thev U-sh'aped standard ll extends downwardly from lthe frame l and is braced by diagonal braces l2.

To the lower end of this standard is Secilred Vthe shoe .13 which serves to, smooth the bottom of the ditch in readiness for the placing L.

vof the tile. his U-shaped standard also supportsthe box la, which is open aboveand at the rear end and serves to.V maintain the tch, -until the `tile can kbe laid. W Y y, VAll the parts heretofore described are old in the art and no claim is made tht-net()7 my invention'consisting in` the Vmechanism will now describe for the purposeof conveying dit-eh;l A A K A- l Extending laterally 'from the lframe fare the frame members l5 'to .which is secured the forward part 16 ofthe back filler conveyor frame; The rearward part 1T 'ofthe back filler conveyor frame ishinged'to .the rear end ofthe forward part and on the hinge pin i8 are journalled one or'more rollers 19.` A conveyor belt 2O passes round rollers 2l at theforward end of the forward f part of the back filler conveyor framefand the rear end of the rearward part thereof.

Qtsef cured to the spindle ofthe forward',roller-"21 of the back filler conveyor belt. f VThe pi voted rearward part of the back filler conveyor frame iS supported in the foli'g'iw ing manner.' Apost25i xte'nded npjnoin the iJ1-shaped standard lvl so as to'for'm" effect an u'pward extension the'rf-oitf. v At the upper end of this postisfjournzilledja guide Ypulley' 26. Over this pulley entendsla wirel i stayr 27, the rearward .end `which is con-1 nec-ted 'with yoke connocted withthe sides 4"of the rearward part 'ofthe back .filler conveyor frame 'l y l y* 25 the stay passes .round a` ginde'pul'ley' 29 journalled on the frame l', theneepassin Y provided with a hand wheel lby means of vto a drum vBO;journalled on thefraime 1an 1 whichit may be rotated. A' pawl and ratchet device 32 is provided whereby the drum may be locked as adjusted.

At the rear end of the part 17 of the bach: filler conveyor frame are secured the forwardly extending brackets 33 carrying a spindle 34 forming an axis suitably connected to the under side ot the tilting chute back liller conveyor.

35. It! will be noted that the axis of the chute is located below the middle oiC the chute and that the Ychute is suitably positioned to receive 'the discharge from the l/Vith this arrangement the chute tends to remain tilted either in one direction or the other so that the soil delivered from the back filler conveyor may either vbe discharged into the ditch as in- Vdicated in full lines in the drawings or entirely from` the shoe Y'i3 through the me- "diuin of thel frame l, and is so balanced that no undue strains are imparted to the frame or other parts of the dinger, By suitably elevating the rearward part ot the conveyor'through the medium oit the Vstay 27 and by suitably tilting the chute 35, vthe dug soil may be deposited in any position desired within Vthe limits ot the adjustment.

lThe extent to which dug soil is elevated.

after passing from the digging wheel ben ing considerably less than when the soil is elevated and deposited on the spill. bank as is now commonly done, the power `consumed in the operation of the device is no greater `than in the old type ot machine and the labor and expense ot back lilling as arseparate operation is entirely avoided. What I claim is Y l Y l. In a ditching machine, the combination of a frame; ditch digging and soil elevating apparatus carried therebygmeans for discharging the dug soil laterally; 'a

trench bottoni shoe; a standard rigidly sup-.

porting the shoe. icrointhe traine; a rear wardly extending back-filler conveyorV trame VVhaving its forward partconnected to one sideV ot the trame; a post extending up f from the standard aforesaid; astay connected to the rear end ot the conveyor frame extending over the post and connected at its forward end to tlieiirame; and

a suitably driven endless belt carried by the said conveyor' frame adaptedto receive the i laterally discharged soil and convey it rearwardly. 2. VA ditching machine, constructed .asv set -to raise and lower the rear part of the conveyor frame. y Y 3. In a ditching machine, the combination of a frame; a ditch digging and soil relevating wheel carried thereby and adapted to discharge within its own periphery; means for receivingthe soil dropped Vfrom the wheel and dischargin@ it laterally; a trench bottom shoe; a standard rigidly supporting the shoe 'from the trame; a rearwardly extending back-filler conveyor traine suitably supported at one side ot' the traine and vertically braced trom the trench bottom shoe; a suitably driven endlessbelt carried by the said conveyor traine adapted to receive the laterallj/.f discharged' soil and convey it rearwardly and a laterally directed chute beneath the rear end of the conveyor.
